How many calories should I eat a day?

I say every human needs to consume around 1800-2200 calories a day to live. If you are a smaller person you can eat less, if you are a bigger person eat more, if you are highly active person eat more as well.

A quick and easy way to estimate this daily caloric need is to divide your weight in kilograms (bodyweight/2.2) multiply by 35 and minus 550
